Alright, got 510 adapter to work with Nano over the weekend & began to fool with it tonight. Figured I'd give this thing a fair enough chance.
It's not heating the atty.
I tried with a 901 atty--battery is good, hitting fine.
I screw on the adapter, snug but not too tight. I screw on 510 atty all way down untill holes are lined up with notches.
I drip 2.5 drops of liquid into atty.
Nothing. Even if it were dry, the atty should be warmed up, correct?
What am I doing wrong, please?
Also.....in the center on either side of adapter--rubber or glue?
